Fears are tricky, sometimes it makes us have the wrong dreams. Are you taking the dream interpretation class? It helps a lot to understand dreams. Pray, trust in god. He only has good things for you.
And no, I don’t think this is a dream about your future marriage and divorce. God doesn’t work like that in our lives. What would be the point in scaring you like that? He is a loving Father who wants to give you peace and love not anguish and despair.
